(57) [Summary] [Problem] It is possible to perform appropriate viewpoint tracking control when displaying a three-dimensional image in a window that can be displayed in an arbitrary size at an arbitrary position on a display screen. I do. A display control device that generates a light directivity for allowing a parallax image to be observed by right and left eyes and enables a three-dimensional image to be observed. A reference position for tracking the viewpoint is acquired based on the position of the center of gravity of the three-dimensional display window (S201 to S201). S203, S208). Then, the light directivity is controlled based on the detected viewpoint position and the acquired reference position, and the viewpoint tracking control is performed. |
